Mercury removal process and equipment

The invention discloses a demercuration process and equipment, which comprises the following steps: putting a material to be treated into a hearth which is provided with a plurality of heating areas which are communicated in sequence and are provided with infrared heating devices at the bottoms, and heating the material through the infrared heating devices, so that the material is decomposed into mercury vapor and slag to realize demercuration of the material; due to the fact that the hearth is provided with the multiple heating areas which are sequentially communicated, and the infrared heating device capable of independently controlling the temperature of each heating area is arranged at the bottom of each heating area, the infrared heating devices can automatically heat and control the temperature of the heating areas where the infrared heating devices are located so that mercury-containing waste materials in the heating areas can be heated to the proper temperature. And mercury in the waste is converted i
